How NG911 ESInet Makes PSAPs More Resilient and Effective

Posted in All, NGA911 on May 16, 2023

In the past decade, there has been a significant shift in public safety communications. Legacy 9-1-1 systems cannot support current technological infrastructures, and there is a universal need to upgrade emergency services. 

Many states and jurisdictions have changed traditional methods of communication by adopting NG911 (Next Generation 911), an Internet Protocol (IP) based system. A significant component of NG911 is the Emergency Services IP Network (ESInet), connecting Public Safety Access Points (PSAPs) while allowing for seamless communication between emergency service providers. 

In this blog from our trusted NG911 providers at NGA, we’ll discuss NG911 ESInet, how it works, and the benefits for emergency response.

What is An ESInet Exactly?

The National Emergency Number Association (NENA) defines an ESInet as an Internet Protocol (IP) network explicitly managed for 9-1-1 emergency response communications. Multiple 9-1-1 agencies can share an ESInet network for professional public safety purposes.

ESInet provides a seamless IP-based network for first responders to communicate with each other and receives emergency calls. It connects PSAPs, emergency service providers, and related entities. 

PSAPs are the primary contact points for emergency calls, so the connections must be of the highest quality. ESInet provides a resilient, flexible network that facilitates connections across different agencies.

How Does ESInet Work? 

ESInet merges the functionalities of voice call infrastructure, data transmission, and incident management systems into one IP-based network. This merger acts as a central hub, allowing different service providers to link up. 

When paired with NG911 technology, this IP network opens the door for a host of new multimedia capabilities that support high-performance emergency services. NG911 ESInet allows various modes of communication, such as voice, video, and data, to reach every responder on the network.

Understanding How ESInet Helps with Resiliency

An ESInet that runs on the secure IP and cloud based networks of NG911 are vital for resiliency and redundancy because they provide an alternative way of communication when traditional phone lines are down. The IP-based network also makes it easier to expand services and adapt to emergencies. This crucial resiliency feature means that in the event of a disaster, emergency responders can continue to provide life-saving services.

Helping PSAPs Become More Effective

The most significant advantages that the ESInet provides is the accessibility to multimedia communication and integration into existing workflows. With the use of ESInet, emergency response personnel can take advantage of video tools and data transmission to exchange relevant information in real-time. This feature improves incident management reducing response times and improving outcomes.

ESInet: Benefits for Emergency Response  

Seamless Interoperability: One of the primary benefits of ESInet is the seamless interoperability it provides. With the use of a ESInet, different agencies, jurisdictional boundaries, and emergency services providers can access a single network, thus ensuring a quick response to emergencies.

Compatibility with Different Devices: Since NG911 ESInet works on the internet protocol, they can easily integrate with mobile phones, computers, and other types of devices. This compatibility helps to streamline communication and provide critical location data during an emergency. Responders can locate the caller through the voice call and gather additional data through sensors and smart devices. They can easily access the data through the IP network, no matter how it was obtained.

Improved Location Accuracy: ESInet has made significant improvements in how emergency services providers can locate individuals accurately in an emergency. The network uses location accuracy technologies, including GPS and GIS to identify the exact location of a caller and provide critical emergency services.

Reduced Response Time: With ESInet, emergency service providers now have a better way of gathering information on an emergency in real-time. The network provides access to relevant information such as location, danger level, and nature of the emergency call, all of which result in quicker response times.

Enhanced Collaboration: ESInet promotes collaboration among different agencies. With its shared network, first responders can communicate and collaborate in real-time, leading to more efficient emergency response, and more effective resolution of incidents.

ESInet Implementation: Why It Matters 

ESInet must be implemented carefully, with the right hardware and network protocols, in order to provide reliable services. NG911 standards have been established to ensure a consistent approach to ESInet implementation.

ESInet is implemented on a regional, statewide, or national level, depending on the area being served. They require robust broadband infrastructure and the utilization of all-IP communication technologies to deliver fast, reliable communications for emergency calls and data.


ESInet offers a reliable, secure, and flexible communication infrastructure. Collaboration is ever more critical to emergency management in today's environment, and NG911 ESInet offers that promise. Emergency services providers can leverage the multimedia resources to reduce response times and improve outcomes. The critical resiliency and redundancy features keep PSAPs operational, even in the event of a disaster. 

Overall, it's clear that ESInet provides a tremendous benefit to emergency services providers and helps make PSAP more resilient and effective.
